Summary: ADCS stands for Attitude Determination and Control Systems, which in basic terms is how a satellite orients itself in orbit. For optical and communication systems orientation is essential to being fully functional. Spacecraft control is an important concern and it is what motivates our ADCS group. We look into various types of control such as Spin Stabilization, Gravity Gradient, Three-Axis Control, and Formation flight. To achieve these control modes we utilize technology such as Reaction Wheel Assemblies, Control Moment Gyroscopes, Magnetic Torque Rods, and Thrusters. The control equipment itself is comprised of sensors like GPS, Star Trackers, Limb Sensors, Rate Gyros, and inertial measurement units. Control Systems utilize flight dynamics such as Euler Angles, and Quaternions.
